I have observed more than a few people argue that potency/potential is best left out of natural philosophy because it is, in principle, not empirically observable. Only act can be observable, hence, being good modern empiricists, we have no need for potency. — Count Timothy von Icarus
I'm just trying to understand why 'we never see material things directly' is qualitatively different from a claim like 'we only ever digest what we consume'. — cherryorchard
... For instance, is 'we only ever hear sounds' a meaningful statement? — cherryorchard
I think elements of it are more appealing today given the possibility of humanity hitting the singularity increasing. It is within reason that if such an extraordinary event was to happen then practically everyone would have access to what would be limitless resources. Therefore, within Communist ideologies there could be some useful applications for such a transition. — I like sushi
And now when even the CCP looks more like fascist than communist and time has past from the days of the Soviet Union, things seem even more nostalgic. — ssu
In that sense we would say, "If language is to have meaning, then the Contrast Theory must hold." The relevant contrast here is the scenario where language has no meaning, and authors like Aristotle to not deny this at least as a logical possibility. — Leontiskos
Austin spends quite a lot of time in 'Sense and Sensibilia' explaining that there is no point in claiming that we only ever see things indirectly, just precisely because, if that is the case, we no longer have any idea what seeing directly would even mean. There would no longer be any such thing as 'seeing directly'. And thus (Austin argues) the term 'seeing indirectly' when used in this way appears to mean something but actually doesn't. — cherryorchard
But maybe Gellner is right that this doesn't hold. If a child asks me what my coffee machine is for, I will explain that it makes coffee. And this explanation strikes me as perfectly valid, even though it is not possible to imagine any other kind of coffee machine. We simply have no concept of what such a machine would be like. That doesn't mean my explanation was wrong, does it? Or that I was using language incorrectly? — cherryorchard
Mystical-like states of consciousness may arise through means such as psychedelic substances, but may also occur unexpectedly during near-death experiences (NDEs). So far, research studies comparing experiences induced by serotonergic psychedelics and NDEs, along with their enduring effects, have employed between-subject designs, limiting direct comparisons. We present results from an online survey exploring the phenomenology, attribution of reality, psychological insights, and enduring effects of NDEs and psychedelic experiences (PEs) in individuals who have experienced both at some point during their lifetime. We used frequentist and Bayesian analyses to determine significant differences and overlaps (evidence for null hypotheses) between the two. Thirty-one adults reported having experienced both an NDE (i.e., NDE-C scale total score ≥27/80) and a PE (intake of LSD, psilocybin/mushrooms, ayahuasca, DMT or mescaline). Results revealed areas of overlap between both experiences for phenomenology, attribution of reality, psychological insights, and enduring effects. A finer-grained analysis of the phenomenology revealed significant overlap in mystical-like effects, while low-level phenomena (sensory effects) were significantly different, with NDEs displaying higher scores of disembodiment and PEs higher scores of visual imagery. This suggests psychedelics as a useful model for studying mystical-like effects induced by NDEs, while highlighting distinctions in sensory experiences. — Martial, Charlotte & Carhart-Harris, Robin & Timmermann, Christopher.

Anyone read these, any or all of of Pratchett? Thoughts? — Amity
BTW, why do you think that the geocentrists in ancient times and middle ages were wrong? What was their mistake? — boundless
The stars and the Sun do orbit the Earth in the earthbound frame — SophistiCat
They do not. — AmadeusD
"The Sun and the stars move from east to west" is a good descriptions of appareances. In this sense, it is 'true' and 'valid', yes.
The problem is the interpretation that we give to that statement. The ancient and medieval geocentrists clearly implied that such a statement described the 'external world as it is': the apparent motion of the celestial objects, to them, wasn't a mere appearance but the 'real motion' of the celestial objects.
They clearly didn't consider their model as a mere 'predictive model' but as an accurate description of the 'external world as it is'.
BTW, clearly we still use a 'geocentric model' in our daily lives, for practical purposes. As you say, it correctly describes the appearances. But we recognize, on reflection, that these appearances are mere appearances, so to speak.
So that's why I said that the statement "The Sun and the stars move from east to west" is provisionally/pragmatically true. But if it's interpreted in the way the ancient and medieval geocentrists did, it's false. Their mistake was an incorrect interpretation of appearances.
Do you agree with my analysis? If not, how do you explain the fact that those people were mistaken? — boundless
It is not veridical to claim the stars and Sun orbit the Earth. — AmadeusD
Not sure if you are disagreeing with me or not. If by 'taken literally' one means that it correctly describes the appearances then, yes, I agree that it can be said to be 'literally true'.
On the other hand, the 'geocentrists' believed that our experience was totally veridical: the Earth was at the center of the universe and didn't move and the Sun revolved around it. It wasn't a mere 'it appears as if' but 'it appears because it is so'. In other words, they were extremely naive realists. — boundless
I'm not sure. Suppose an archaeologist uncovers tablets on which are inscribed a lost language. What did the archaeologist discover? Seemingly, information that can no longer be decoded. Years later, the language was translated. Did the information spring into being? Or was it always there? — hypericin
The statement 'the Sun and the stars revolve around Earth and they move from east to west' is, if taken literally (i.e. as an accurate description of 'what really happens in the external world'), false. — boundless
I think the salient point is that there can be multiple reductive explanations from different perspectives. So, to say that I went to the shop because I was thirsty is a reductive explanation, as much as saying I went to the shop because of certain neural activity is. Such different explanations do not contradict, and should not exclude, one another. — Janus
So for example, the epiphenomenalist might say consciousness does no work, just "goes along for the ride", so to speak, but that would be an illegitimate elimination of one reasonable way of explaining human behavior. I think what puzzles people is that we cannot combine the two explanations or achieve any absolute perspective which would eliminate one and retain the other. 'Either/ or' thinking seems to generally dominate the human mind.
Have you read the book? I feel like it sort of gets misrepresented in reviews because the argument really doesn't come into focus until the last chapter. Hoffman's point is an argument about a certain, fairly dominant form of naturalism that imports Kantian dualism into "science." — Count Timothy von Icarus
I agree on the type of error involved. I disagree on the track record of reductionism. How many true reductions do we have? Thermodynamics and statistical mechanics is the canonical example, but it is a rare example. 120 or so years on, the basics of molecular structure in chemistry has yet to be reduced to physics. Reductions are not common. Unifications, the explanation of diverse phenomena via an overarching general principle are far more common. For example, complexity studies explains disparate phenomena like earthquakes and heart beats via a similar underlying mathematics. But of course this does not say that heart beats or earthquakes are "nothing but," the math they share in common. Yet it seems to me that unifications are very often misunderstood as reductions. — Count Timothy von Icarus
That and facts about composition is misunderstood as a reduction. To be sure, all cells are made from molecules. All molecules are made from atoms. This isn't a reduction. You can't predict how a molecule works from theory in physics, you need all sorts of ad hoc empirically derived inputs for it to work. — Count Timothy von Icarus
But I think the error you identify is directly related to smallism and reductionism. The justification for the causal closure principle is normally that minds are "nothing but" brains/bodies, and the brains and bodies are "nothing but" atoms and their constituent particles. Particles are the smallest structure and thus most fundemental. Everything is "nothing but" these, and so everything is describable in terms of their interactions. This makes all other causal explanations duplicative. At best they are a form of data compression. And so this makes motive irrelevant and conciousness epiphenomenal. — Count Timothy von Icarus
Exactly...the reductionists seek to analyze the physical in terms of the mental (idealism) or the mental in terms of the physical (eliminative physicalism). Tendentious thinking prevails on both sides. — Janus
I think Plantinga's argument is ultimately just one simplified form of an entire web of arguments that can be made vis-á-vis psychophysical harmony, causal closure, and epistemology. Hoffman is able to flesh this out with some models and empirical results. Is it air tight? No. But then again what they are arguing against is also a position that is not airtight. Yet this position, like reductionism, is one that seems to demand that it be "assumed true until decisively proven otherwise," and I'd venture that there is not good grounds to accept this — Count Timothy von Icarus
Physicalism is normally defined in terms of casual closure. Reductionist materialism also assumes causal closure. But if causal closure is true the mental never—on pain of violating the principle—has any effect on behavior. It is just "along for the ride." Everything is determined by particles and how they interact, so no one ever goes and gets a drink "because they feel thirsty" (at least not in the causally efficacious sense of "cause.") — Count Timothy von Icarus
Alvin Plantinga's rather fun argument called the evolutionary argument against naturalism (EAAN). If it comes up with apologists a lot these days. Here's a basic overview:

The OP raised this in relation to Hoffman's theory too. — Tom Storm
Have you made it to the last chapter? He sort of turns everything he has said on his head. His point is that a common way of looking at the relationship between mind and nature is self-refuting. Plantinga has previously made a similar argument. I don't think this is a bad argument, although the way it is framed it does seem like he is refuting himself as well. But I take it that this is exactly the point, his position is self-refuting because it's situated in popular assumptions that are self-refuting. — Count Timothy von Icarus
To those who have seen Tarkovsky's Solaris: what do you make of the surprisingly long (even for Tarkovsky, I think) bit where the ex-pilot Burton is in a car going through a big city, along motorways, overpasses and tunnels?
Normally I like the slow stuff in Tarkovsky, but this seems awkward and perplexing. The sounds, which I think are meant to be futuristic, do not even seem to match the familiar urban scene.
It ends with an abrupt cut to the wildflower meadow at Kelvin's house (which looks exactly like a Russian dacha), so it looks like a juxtaposition between inhuman modernity and bucolic serenity, but it still seems odd. My guess is that in fact, Tarkovsky made do with footage that did not turn out as well as he'd imagined. — Jamal

Just watched "Patterson" with Adam Driver. A sweet, understated, lovely little movie. I can't remember when I've watched another I enjoyed more. I haven't seen Driver in anything else, but he was wonderful in this. — T Clark
I'm really glad people are interested, but I will remind you that there is an email address set up for questions and potential solutions because I sent this to a couple of forums and fifty philosophy departments, so trying to keep up with communication in every avenue is going to be difficult — Dan
I think we can make an even stronger statement: the only way that the usual probability rules (normalizability, additivity) can be satisfied on an infinite sample space is if all but a finite number of simple outcomes have probability zero. — SophistiCat
I can try to give you an example of "an algorithm that gives all integers (without limit) SOME probability of happening" if you like. — flannel jesus
This algorithm is theoretically capable of randomly producing ANY of the infinite sequence of integers, but it preferentially chooses lower numbers. — flannel jesus
I just had a train of thought I thought might be vaguely interesting:
1. With an infinite number of options, not all options can have equal probability. — flannel jesus
I have a metaphysical probability question:
Suppose there are an infinite number of parallel Earths. Alice uses a teleporter to teleport to a random Earth. Bob tries to follow Alice, but he has to guess which Earth she teleported to. What are Bob's chances of getting it right? Is there any way for a teleporter machine to randomly select an Earth out of an infinite number of them in a finite amount of time, or is there always going to be, practically speaking, only a finite amount of Earths for Alice to teleport to because of the limitations of the machine? — RogueAI
What if I cheat and say the teleporter pokes a hole into the universe and the universe somehow, through a mysterious process, randomly picks an Earth out of an infinitely large ensemble for Alice to teleport to? Are Bob's chances of teleporting to Alice's world zero? — RogueAI
In fact, this means that is some kind of hidden collusion between these candidates. — Linkey
This is explained by the fact that the 1% of richest people control the mass media and are motivated to keep this situation as long as possible. — Linkey
